For the past 2 days, my player has been locking up when trying to view any NetFlix content.

I have noticed a couple of symptoms:
1) The box *seems* to take longer to boot than it used to. This may just be perception, but I timed it and it took almost 4 minutes to start up (unfortunately, I have no "control data" to tell me how long it was taking before this problem appeared, so it really could just be psychological).

2) While browsing my Instant Queue, the navigation is very responsive, but as soon as I click "Play" from a title menu, the device hangs for nearly a minute (this used to be instantaneous).

When the player finally begins to retrieve the selected title, it hangs at the black screen: no change in the progress bar and no quality dots/ indicators appear. It will remain in this state until it is rebooted (literally, my kids left it for hours waiting for me to get home from work).

A couple of things about my setup:
1) I have a 3Mb DSL connection, which is operating normally (every other device on my home network-- and there are 12 of them-- can reach the Internet).

2) My player has the latest software (v1.5b909).

3) The network status reported by the player is OK - it is receiving an IP address.

4) The "secret screen" shows that the player is registered.

5) There are about 120 titles in my queue. All of the "ad box" images appear after the unit has booted up.

Is anyone having similar symptoms? Any thoughts? Does anyone know of any other secret screens with other diagnostic tools?

I'm getting the same sort of problem. Retreiving screen hangs for a second, three red ticks on the bar, and then back to the queue. Can't watch a thing. Checked wireless router and everything seems ok. No changes were made on my part in the past three days. Just stopped working. >>

I'm seeing one of these reports once in a while, and I'm looking in to it.
Start with a factory reset. Settings>General>Factory reset.
You'll have to re-register the box with your Netflix account after this.

Those are the same exact symptoms which have made my box useless since early January.

I've done factory reset/re-register on my own and with Roku phone support. The phone support person finally said it's due to a problem with the 1.5 update, build 901, and that my box would be updated again "within a week" to resolve the problem.

It's been over two weeks since I spoke to them. Still waiting, still no update. I'll be calling them later. Good luck!
